MACHINE FOR CORRUGATING METAL COVERS FOR SEALING JARS.

SPECIFICATION forming part of Letters Patent No. 231,917,'dated September 7, 1880.

' Application filed June 1, 1880. (No model.)

To all whom it may concern:

Beit known that I, LOUIS LENGLET, of St. Louis, in the State of Missouri, have invented a new and useful Improved Machine for (Jorrugatiug Metal Covers used for Hermetically- Sealed Jars, of which the following is a specification.

This invention is specially designed to be used in connection with the mode and means I employ to form a hermetically-sealed glass jar, and for which I have applied for Letters Patent of the United States.

More specifically stated, by the use of my machine the annular wall of the metal cover placed in the corrugated neck of the jar, can be the better shaped and made to have counterpart corrugations, further, be pressed in and closely joined against the said corrugations in the neck of the jar, and thus effectually close the joint between the said contiguous corrugated surfaces, and perform this nature of work with a great saving in time, labor, and expense. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved machinein its entirety as ready for application and use. Fig. 2 is a central plan sec tion taken on line :20 00, showing the manner of securing the fulcrum of each lever. Fig. 3 is an enlarged side elevation of the lower half of the machine,'the dotted lines indicating the original position of each lever, while the parts shown in full lines are represented as having been drawn together and placed in the neck of the jar and its cover for the purpose of corrugatin g the latter.

Similar letters refer to similar parts th rou ghout the several views.

A is a screw-clamp to secure the machine to a table or support. B is a vertical shaft or rod, fitted to turn in the end bearings of the frame of the clamp. (See Fig. 1.) B is a belt-wheel to turn with the shaft B, hence is rigidly se cured near the upper end of said shaft, as indicated in Fig. 1. The lower end of the shaft B is secured to the socket of a plate, (3, by a set-screw, c. This screw passes through the socket and engages the shaft, as shown in Figs. 1 and 2. Thus the shaft and plate G can be rigidly united to operate together.

D represents in its entirety each of the four levers. They are each pivoted in a vertical condition to each of the slotted bearings (marked 0) of the plate 0, as shown in the tigures. By preference a single strip or wire, 0 is employed, instead of separate fulcrum-pins, to pivot or fulcrum all said levers to their respective bearings at the four corners of the plate G. (See figures.) The upper arm of each 6 lever has its upper end'passing through the radial slots 0 seen in each of the arms of a horizontal wheel, E, as shown in Fig. 1. The wheel E, with the upper ends of each lever passing through its radial slots, is rigidly secured to turn with the vertical shaft B, as

shown in Fig. 1. The slots 6 are elongated, so as to afford suflicient play for the movements of the upper arm of eachlcver. Here1t can be stated that each lever so fulcrumed audio arranged is capable of being moved inward and outwardthat is to say, the operator grasps with the hand each lever by its lower arm or end, and in pressing all said levers at one time inward or toward each other the upper part or arm of each lever will move or spread outward. The-said motions on part of the levers is indicated more specially in Fig. 3, in which, as before stated, the original position of the leversis indicated by the dotted lines, (also said original position is shown in Fig. 1,) while the full lines in Fig. 3 show the levers sufficiently pressed inward and held until the glass jar, by its neck containing the metal cover, has been placed in engagement with the lower ends of said levers.

F represents a rubber strap, to serve as a spring to return each lever to original position after having been pressed inward,and to continually act to spread said levers outward and press against the metal cover when the latter and the glass jar are placed. in operative engagement with the machine. The rubber strap F, for the purposes mentioned, is simply passed around all the levers near their upper ends, as shown in Fig. 1.

f (see Figs. 1 and 3) are rollers turning on the lower end of each lever, so as to ease the operation of the machine and facilitating the shaping of the metal cover.

The nature of the work the machine is designed to perform is shown in Fig. 3, viz: to

press the annular wall of the metal cover against the interior corrugated surface of the neck of the jar, and at same time and in the like places to crimp or corrugate said cover that a most perfect closure or joint shall exist between the two contiguous surfaces of the neck of the jar and cover. Therefore to apply and use the machine the operation is as follows: The operator first grasps all the levers at their lower ends, and at one and the same time forces or presses them sufficiently inward or together to enable the glass jar containing the cover to engage the lower end of the machine, as indicated in Fig. 3. The said Fig. 3 shows the levers in position to shape the metal cover to have the like lower corrugation that exists in the neck of the glass jar.

When the lower ends of all the levers engage the proper part of the metal cover-via, where the corrugation is to be made in the lattera rotary or reciprocating motion is imparted to the machine by belting from powersource operating the belt-wheel and vertical shaft. The levers are all thus rapidly rotated or reciprocated at same time, subject to the tension of the spring F, until the metal of the cover has been properly shaped to have the counterpart corrugation and pressed closely against the corrugation in the neck of the jar. When the lower corrugation has been thus made in the cover the glass jar, with its cover, is slightly lowered to properly position said parts with relation to the lever ends to form the upper corrugation.

What I claim is The combination of the screw-clamp A, its shaft B, carrying belt-wheel B, horizontal wheel E, having slots 0 in its radial arms, the system of levers D, pivoted to a bearing-plate, C, said levers having rollers f at their lower ends, and a suitable spring surrounding them all at their upper ends, all said parts constructed to operate in the manner and for the purposes set forth.
